Here is a well documented DIY tutorial on how to build a basic electronic speed controller. The article takes your through a ground up process on how to build the circuit as well as how to program the PIC that controls the speed controller.

The article does indicate that the design does lack sophistication, but this is a good place to start. You could use this design as a learning process and then modify the circuit as needed.

[…] It might be “yet another” «device» controller that operates over phone-line, but this one works for sure The task was to build a device that connects to the phone line and has a relay as an output switch. It should also sense if the connected «consumer» is turned-on or off and report to the administrator at the other end of the phone line. The administrator would then call-in the device, log in with the password, and check the state of «consumer», turn it on or off, change password or some other settings. Current version has only one relay. [via] […]

hey i need to vary the speed of my dc motor and all i’ve got is a frequency that varies from 0 to max… i can control the frequency. now i want to control the supply to the motor from a 12v battery to the motor using this frequency. can i use the controller mentioned above. if yes can u guide me how..
